A policeman moving on a highway with a speed of \( 30 \mathrm{~km} \mathrm{~h}^{-1} \) fires a bullet at thiefs car speeding away in the same direction with a speed of \( 192 \mathrm{~km} \mathrm{~h}^{-1} \). If the muzzle
P speed of the bullet is \( 150 \mathrm{~m} \mathrm{~s}^{-1} \), with what speed does the

W bullet hit the thiefs car?
(1) \( 120 \mathrm{~m} \mathrm{~s}^{-1} \)
(2) \( 90 \mathrm{~m} \mathrm{~s}^{-1} \)
(3) \( 125 \mathrm{~m} \mathrm{~s}^{-1} \)
(4) \( 105 \mathrm{~m} \mathrm{~s}^{-1} \)
